Supported Disk Shelf Combinations and HBAs
Disk shelves are supported by specific HBAs in the controller, and can be combined in
certain configurations within a system. Use the following table to determine the HBA
type required by each disk shelf model.

The following table describes the disk shelf models that can be used together for each
controller configuration, starting with software release OS8.7.0. See Cabinet and Cabling Guidelines for disk shelf intermixing
guidelines and all-flash disk shelf usage. To understand which controllers support which
HBA types, see Maximum Disk Shelves per Controller Configuration.
Note -
For optimal performance, do not attach all-flash and non-all-flash disk shelves to
the same SAS-3 HBA.
